TECHNICAL FIELD/FIELD OF THE DISCLOSURE

The present disclosure relates generally to oilfield equipment, and specifically to integrated data recorders for oilfield equipment.

BACKGROUND OF THE DISCLOSURE

Wellbores are traditionally formed by rotating a drill bit positioned at the end of a bottom hole assembly (BHA). The drill bit may be actuated by rotating the drill pipe, by use of a mud motor, or a combination thereof. As used herein, the BHA includes the drill bit. Conventionally, BHAs may contain only a limited number of sensors and have limited data processing capability. The operating life of the drill bit, mud motor, bearing assembly, and other elements of the BHA may depend upon operational parameters of these elements, and the downhole conditions, including, but not limited to rock type, pressure, temperature, differential pressure across the mud motor, rotational speed, torque, vibration, drilling fluid flow rate, force on the drill bit or the weight-on-bit (“WOB”), inclination, total gravity field, gravity toolface, revolutions per minute (RPM), radial acceleration, tangential acceleration, relative rotation speed and the condition of the radial and axial bearings. The combination of the operational parameters of the BHA and downhole conditions are referred to herein as “drilling dynamics.”

To supplement conventional BHA sensors, drilling dynamics data may be measured by drilling dynamics sensors. Measurement of these aspects of elements of the BHA may provide operators with information regarding performance and may indicate need for maintenance. Conventional downhole drilling dynamics sensors are located on a dedicated sub used to house the sensors. The conventional downhole drilling dynamics sensor sub is mechanically coupled to a portion of the drill string or the desired downhole drilling equipment, directly or indirectly. Conventional drilling dynamics sensor subs also require physical connections to be made to retrieve measurements made by the drilling dynamics sensors.

In some embodiments, carrier sub 320 may include male threaded connection 322 and female threaded connection 324 for threaded insertion into the drill string. Although not depicted, in other embodiments, carrier sub 320 may include two female threaded connections or two male threaded connections.

Friction reduction tool 500 may include amplifier section 510 in mechanical connection with pulser section 520. Pulser section may include valve section 540 in mechanical and fluid and/or electrical connection with power section 530. In the embodiment shown in FIGS. 6 and 6A, integrated data recorder 100 may be positioned in friction reduction recorder slot 535.

As shown in FIG. 6 , friction reduction recorder slot 535 is positioned within amplifier section 510.

Integrated data recorder 100, 200 within carrier sub 320 may be used in conjunction with a variety of tool subcomponents that make up tool 300. In one non-limiting example, integrated data recorder 100 may be used with a friction reduction tool, as shown in FIG. 6 and a mud motor, as shown in FIG. 5 . As discussed above with respect to mud motor 400, one or more of rotor catch recorder 425, top sub recorder 485, and bit box recorder 465 may be positioned in mud motor 400. Friction reduction recorder slot 535 may be positioned within friction reduction tool 500. As shown in FIG. 7 , friction reduction tool 500 and mud motor 400 may be mechanically coupled by intermediate drill string section 710.

In another embodiment, integrated data recorder 100, 200 may be positioned within a drill bit. In some embodiments, the sensors within integrated data recorder 100, 200 may be used to determine bit dynamics and the operating condition of the bit. FIGS. 8A-8D depict locations in which integrated data recorders 100 may be positioned within drill bit 800. FIG. 8A depicts shank slot 810. FIG. 8B depicts blade shoulder threaded slot 820. FIG. 8C blade threaded slot 830. FIG. 8D depicts body threaded slot 840.

FIG. 10A depicts integrated data recorder 200 positioned in blade 1060 of stabilizer body 1010. In some embodiments, integrated data recorder 200 may be positioned in between adjacent blades 1060 in stabilizer body 1010. FIG. 10B depicts integrated data recorder 200 positioned in blade 1060.

FIG. 11 depicts ball seat assembly 1100 for use, for example, with a coring assembly. Ball seat assembly 1100 includes inner bore 1110 in which ball seat 1120 is positioned. In the embodiment shown in FIG. 11 , integrated data recorder 100, 200 may be positioned within ball seat slot 1130 formed within ball seat outer wall 1140 proximate ball seat 1120. In certain embodiments, integrated data recorder 100, 200 may be positioned within near-bit stabilizer 1000, 1050 as discussed herein above, and another integrated data recorder 100, 200 positioned within ball seat assembly 1100. The integrated data recorder 100, 200 within near-bit stabilizer 1000, 1050 may measure shock, vibration, rotation speed (in RPM), inclination, toolface, total gravity field, radial acceleration, tangential acceleration or a combination thereof, for example. Sensor measurements taken by sensors within near-bit stabilizer 1000, 1050 in combination with sensor measurements taken by sensors within ball seat assembly 1100 may determine drilling dynamics throughout the coring assembly. In some embodiments, outer wall 1140 may be formed at least partially from an electrically, magnetically, and/or electromagnetically transparent material aligned with integrated data recorder 100, 200

FIG. 12 depicts integrated data recorder 100, 200 positioned within stick-slip mitigation tool 1200 in stick-slip tool slot 1210. Stick-slip mitigation tool 1200 may also be referred to as a constant weight-on-bit tool. FIG. 13 depicts integrated data recorder 100, 200 positioned within turbine 1300 in turbine slot 1310. In some embodiments, integrated data recorder 100, 200 may be positioned within rotor 1315, stator 1320, or output shaft 1325 of turbine 1300.

In some embodiments, tool 300 into which integrated data recorder 100 or integrated data recorder 200 is integrated may be a surface tool used as part of a drill or tool string or may be coupled to a piece of equipment used with the drill string. As a nonlimiting example, FIG. 16 depicts drilling rig 600, which may be a drilling rig, geothermal drilling rig, coring rig, or mining rig. Drilling rig 600 may include rig floor 601, substructure 603, and mast 605. In some embodiments, drilling rig 600 may include top drive 607. Top drive 607 may include quill 609. Quill 609 may couple to the top of the drill string, depicted as drill string 611, and may be used to rotate drill string 611 during a drilling operation. Top drive 607 may also be used to move drill string 611 vertically within the wellbore. In some embodiments, quill 609 may couple directly to drill string 611 or may, as depicted in FIG. 16 , couple to drill string 611 through saver sub 613. In some embodiments, one or more integrated data recorders 100, 200 may be positioned within one or more components of drilling rig 600 including, for example and without limitation, quill 609 of top drive 607 or within saver sub 613. In some embodiments, integrated data recorder 100 may be at a constant communication with external device 180, which may be a surface device.

In some embodiments, as shown in FIG. 16A, tool joint clamp 614 may be used at the connection between quill 609 and saver sub 613. Tool joint clamp 614 may, for example and without limitation, reduce the likelihood that saver sub 613 is unintentionally unthreaded from quill 609. In some embodiments, tool joint clamp 614 may include slot 616 into which integrated data recorder 100, 200 may be positioned.

In some embodiments, drilling rig 600 may include kelly 615 as depicted in FIG. 17 . Kelly 615 may be coupled to the upper end of drill string 611 and may be used to rotate drill string 611 using rotary table 617. In some embodiments, integrated data recorder 100, 200 may be positioned within kelly 615 or within saver sub 613 positioned between kelly 615 and drill string 611.

In some embodiments, multiple integrated data recorders 100, 200 may be included within a single drill string or tool string coupled to various tools 300 at various locations throughout the drill string or tool string. In some such embodiments, as depicted in FIG. 18 , integrated data recorders 100, 200 may be located within both downhole and surface tools of the drill string or tool string. For example, integrated data recorders 100, 200 may be positioned in BHA near drill bit 800 or in bit box 450 and positioned spaced apart from drill bit 800 such as at top sub 480. Additionally, one or more integrated data recorders 100, 200 may be positioned at a component of drilling rig 600 such as, for example and without limitation, quill 609 of top drive 607, saver sub 613, or Kelly 615. In some embodiments, measurements may be taken with all integrated data recorders 100, 200 as discussed further below.

In operation, the sensors in sensor package 110 of one or more integrated data recorders 100, 200 located in a downhole tool 300 located within the wellbore may measure drilling dynamics data. The drilling dynamics data may be stored in memory module 115, referred to herein as “memory logging,” during the drilling process. When tool 300 is retrieved from the wellbore and positioned at the surface, drilling dynamics data may be retrieved from memory module 115 through wireless communications module 122 without removing integrated data recorders 100, 200 from the downhole tool 300 and may be used by a surface processor such as external device 180. For example, in some embodiments, such as during a drilling, geothermal drilling, or mining operation, tool 300 may be retrieved from the wellbore, drilling dynamics data may be retrieved wirelessly from integrated data recorder 100 or 200, and tool 300 may be redeployed without any disassembly of tool 300 or without physically connecting to integrated data recorder 100 or 200.

In some embodiments, external device 180 at the surface may include a surface processor connected to a cloud data storage and computing server. In some such embodiments, the wirelessly retrieved data may be stored in the cloud data storage and may be processed in the cloud server. For example and without limitation, in some embodiments, a run summary, including rotating hours, flow-on hours, vibration-on hours, shock statistics, stick-slip statistics, or other data gleaned from integrated data recorders 100, 200 may be generated in the cloud server and sent to one or more client devices via the Internet. In some embodiments, both surface recorded drilling dynamics data and downhole recorded drilling dynamics data may be quality-controlled (QC′ ed), in the cloud computing system, and combined with data from a surface Electronic Drilling Recorder (EDR). In some embodiments, a drilling dynamics log and accelerometer/gyro spectrograms, such as in JPEG (Joint Photographic Experts Group), PDF (Portable Document Format), may be generated in the cloud computing system. In some embodiments, one or more pattern recognition algorithms (e.g. based on artificial intelligence and machine learning) may be run on the combined data sets to identify, for example and without limitation, operational anomalies and/or data anomalies.

In some embodiments, the sensors in sensor package 110 of one or more integrated data recorders 100, 200 located at the surface may continuously or continually transmit drilling dynamics data recorded from the piece of surface equipment such as top drive 607, quill 609, saver sub 613, or kelly 615 through wireless communications module 122 for use by the surface processor such as external device 180.

In some embodiments, the surface processor may use the drilling dynamics data for post-run and/or continuous (in the case of surface tools including integrated data recorders 100, 200) evaluation of drilling dynamics, frequency spectrum, statistical analysis, and Condition Based Monitoring/Maintenance (CBM). In some embodiments, frequency spectrum analysis may be done, for example, by applying discrete Fourier transform (or fast Fourier transform) to burst data. In some embodiments, statistical analysis may be done, for example, calculating minimum, maximum, median, mean, mode, root-mean-squared values, standard deviation, and variance of burst data. Statistical analysis may include making histograms of, for example, temperature, vibration, shock, inclination, rotation speed, rotation speed standard deviation, and vibration/shock standard deviation. Temperature histograms may include, for example, accumulating the data points in certain temperature bins over multiple deployments (runs) of the sensors and downhole tools.

CBM is maintenance performed when a need for maintenance arises. This maintenance is performed after one or more indicators show that equipment is likely to fail or when equipment performance deteriorates. CBM may apply systems that incorporate active redundancy and fault reporting. CBM may also be applied to systems that lack redundancy and fault reporting.

CBM may be designed to maintain the correct equipment at the right time. CBM may be based on using real-time data, recorded data, or a combination of real-time and recorded data to prioritize and optimize maintenance resources. Observing the state of a system is known as condition monitoring. Such a system will determine the equipment's health, and act when maintenance is necessary. Ideally, CBM will allow the maintenance personnel to do only the right things, minimizing spare parts cost, system downtime and time spent on maintenance.

Drilling dynamics data, such as high-frequency continuously sampled and recorded data, wherein high-frequency data refers to data at 800 Hz-3200 Hz, may be used for rock mechanics analysis. Such rock mechanics analysis include the analysis/identification of fractures, fracture directions, rock confined/unconfined compressive strength, Young's modulus of elasticity, shear modulus, and Poisson's ratio. Such rock mechanics analysis may be accomplished by combining with surface measured parameters, such as WOB (weight on bit), TOB (torque on bit), RPM (revolutions per minute), ROP (rate of penetration), and flow rate. Pseudo formation-evaluation log, such as pseudo-sonic log, pseudo-neutron log, pseudo-porosity log, pseudo-density log, pseudo-Gamma log may be generated with a combination of the analysis of high-frequency continuously sampled and recorded data, along with surface parameters, and other formation-evaluation data, such as natural Gamma log and other logging-while-drilling (LWD) logs. Alternatively, high-frequency continuously-sampled data (e.g. at 800 Hz-3200 Hz) may be used for real-time rock mechanics analysis. Rock mechanical parameters may also be referred to as geomechanical parameters. Alternatively, pseudo-formation evaluation log, such as pseudo-Gamma log may be generated downhole and transmitted to the surface for real-time geo-steering.

In some embodiments, the sensors in sensor package 110 of each of the one or more integrated data recorders 100, 200 located both at the surface and downhole may be identical. In some embodiments, integrated data recorders 100, 200 located both at the surface and downhole may be operated such that all integrated data recorders 100, 200 record the same data at the same or higher resolution. In such an embodiment, the surface processor may receive and analyze drilling dynamics data from both surface and downhole integrated data recorders 100, 200, gathered by identical sensor packages 110 in both the surface and downhole integrated data recorders 100, 200. For example, the surface processor may compare surface drilling dynamics data with downhole drilling dynamics data to identify operational anomalies and earlier detection of downhole dysfunctions. As a non-limiting example, data from downhole sensors connected to a MWD wirelessly or with a physical connection may be transmitted to the surface. However, the transmission speed of the real-time data via, for example, mud pulse telemetry may be very low, such as at 1-2 bits per second. By correlating the downhole and surface drilling dynamics data recorded by integrated data recorders 100, 200, some correlation of, for example, bit drilling dynamics and surface dynamics data, could be identified. Using this correlation to detect early signs of one or more downhole problems, the surface data can be used to monitor downhole problems and operational anomalies. The surface sensor data may be transmitted to the surface computer at the wireless communication speed, such as at 1-10 gigabits per second in real time. The surface data received at the surface computer may be moved to a cloud computing system via the internet for further real-time and/or non-real-time processing. Due to the limitations to transmission of data from downhole to the surface, the use of surface drilling dynamics data (in conjunction with the downhole data correlation) may allow for better and more economical determinations of downhole problems or operational anomalies. In other embodiments, surface and downhole integrated data recorders 100, 200 may be operated in different modes. In some embodiments, when an anomaly is detected from the surface drilling dynamics data, a rig automated control system may adjust surface parameters until a different or smoother signal is received.

Power from electrical energy source 130 may be supplied to the sensors in sensor package 110. In some embodiments, the electrical power from electrical energy source 130 to the sensors in sensor package 110 is always on (powered up) but at different levels. At the lowest power level, which in some embodiments may be used while integrated data recorder 100, 200 are being transported, integrated data recorder 100, 200 may be in “deep-sleep mode.” In deep sleep mode, the real-time clock, sensors, for example, sensors 111, 112, 113, 114, 116, 117 and 119, memory module 115, and voltage regulator are powered off and processor 105 is placed in sleep mode. In certain embodiments, current consumption of this deep-sleep mode may be between 1 uA and 200 uA. In sleep mode, processor 105 does not function, except to receive a “wake-up” signal. The wake-up signal may, in some embodiments, be received through wireless communications module 122. In some embodiments, integrated data recorder 100, 200 may be placed in deep sleep mode by a software command to processor 105 received through wireless communications module 122. Integrated data recorder 100, 200 may be transitioned from deep-sleep mode to standby mode by communicating the wake-up signal to processor 105 through wireless communications module 122 while processor 105 is in passive mode. In some embodiments, processor 105 may be woken up by one or more active mode predetermined event criteria including, for example and without limitation, an inclination trigger, RPM trigger, temperature trigger, vibration trigger, or pressure trigger, in which a certain inclination of tool 300, rotation rate of tool 300, temperature measurement, vibration of tool 300, or pressure measurement, respectively, measured by one or more corresponding sensors of sensor package 110 of integrated data recorder 100, 200 causes processor 105 to enter the standby or operational state.

Deep-sleep mode may, for example and without limitation, extension of battery life during transportation and/or storage without requiring physical disassembly of integrated data recorder 100, 200. Physical disassembly of integrated data recorder 100, 200 may damage seals, threads, wires, and other elements if done by an unfamiliar technician in a remote location. The recorder may be in “deep-sleep mode” for as much as between 1 month and 1 year before it is sent downhole for dynamics data logging.

In standby mode, processor 105 and at least one sensor (active sensor) of sensor package 110 are active. Digital solid-state sensors may be put into standby mode using a digital command. Standby current to remaining sensors of sensor package 110 may be around 1 μA to 200 uA. Once an active mode predetermined event criterion is met, as determined, for example, by the active sensor, processor 105 sends a command to the remaining sensors of sensor package 110 to begin measurement of data and to memory module 115 to begin logging data (“active mode”).

FIG. 14 is a block diagram of an embodiment of integrated data recorder 100, 200. Integrated data recorder 100, 200 may include sensor package 110 having a plurality of sensors.

The active mode predetermined event criterion may be, for example, a temperature, acceleration, acceleration standard deviation, rotation speed standard deviation, or inclination threshold as determined by the active sensor. The active mode predetermined event may also be a drill string or bit rotation rate threshold. In some embodiments, the active mode predetermined event criterion may be a combination of one or more of a temperature threshold, acceleration threshold, acceleration standard deviation threshold, rotation speed standard deviation threshold, inclination threshold, drill string rotation rate threshold, or bit rotation rate threshold. In some embodiments, the active mode threshold that predetermines event criterion may be stored in digital, solid-state sensors, which may generate interrupt events to processor 105. For example, one non-limiting example of a digital, solid-state sensor with such feature is an I²C digital temperature sensor, Model MCP9800 from Microchip (Chandler, Ariz., USA). Temperature thresholds with hysteresis (e.g. upper threshold and lower threshold) may be stored in MCP9800. In certain embodiments, all sensors are non-active during standby mode and the drill string or bit rotation (using accelerometers, gyros, magnetometers or a combination thereof) may be communicated to and received by integrated data recorder 100, 200 via downlink communication from the surface. In certain embodiments, downlink communication may be accomplished by mud-pulse telemetry, electro-magnetic (EM) telemetry, wired-drill-pipe telemetry or a combination thereof. In other embodiments, downlink communication may be accomplished by varying the drill string rotation rate, for example and not limited to the method described in US Patent Publication No. 2017/0254190, entitled System and Method for Downlink Communication, published Sep. 7, 2017.

In certain embodiments, during active mode, once a predetermined passive mode criterion has been met, processor 105 may send a command to the sensors of sensor package 110 and memory module 115 to return to standby mode, thereby discontinuing measurement of data by the sensors and logging of data by memory module 115. The passive mode predetermined event criterion may be, for example, a temperature threshold, acceleration threshold, acceleration standard deviation threshold, RPM threshold, or inclination threshold as determined by one or more sensors of sensor package 110. In some embodiments, the passive mode thresholds that predetermine event criterion may be stored in digital, solid-state sensors, which may generate interrupt events to processor 105. One non-limiting example of digital, solid-state sensor with such feature is an I²C digital temperature sensor, Model MCP9800 from Microchip (Chandler, Ariz., USA). Temperature thresholds with hysteresis (e.g. upper threshold and lower threshold) may be stored in MCP9800. In one non-limiting example, the digital, solid state sensor made may change from the passive mode (no logging) to the active mode (logging) and from the active mode (logging) to the passive mode (no logging) multiple times, based on one or more, or a combination of event thresholds.

In active mode, sensors in sensor package 110 are turned on for a predetermined duration at a predetermined log interval for measurement of drilling dynamics data. Examples of predetermined duration include 1-10 seconds. Examples of predetermined log intervals are every 1, 2, 5, 10, 20, 30, or 60 seconds and durations between those values. Predetermined log intervals for each of the sensors in sensor package 110 may be the same or different. Predetermined durations for each of the sensors in sensor package 110 may be the same or different.

In certain embodiments, the sensors of sensor package 110 record burst data to memory module 115 at a burst data frequency. In some embodiments, the burst data frequency may, for example and without limitation, be 20 Hz or more, 50 Hz or more, 100 Hz or more, 200 Hz or more, 400 Hz or more, 800 Hz or more, 1600 Hz or more, or 3200 Hz or more. Examples of burst data log interval include every 1, 2, 5, 10, 20, 30, or 60 seconds. The sensor burst data may be buffered in digital sensors in the built-in sensor memory, which may be configured as FIFO (first-in first-out) memory. In certain embodiments, processor 105 does not store sensor burst data in processor's RAM (random access memory), i.e., sensor data is sent directly from the sensors in sensor package 110 to memory module 115. In certain embodiments, processor 105 may store a predetermined number of samples of sensor burst data (for example, just one sample of sensor burst data) in the RAM of processor 105 prior to sending the sensor burst data to memory module 115. In other embodiments, high-frequency sampling data, for example, at 3200 Hz, is continuously stored to memory module 115, such as continuously bursting and recording.

The use of the FIFO memory of a sensor may reduce processor 105 processing capability requirements and processor 105 power consumption. In certain embodiments, the number of the FIFO memories of a sensor may be between 32 and 1025 data points, or between 32 and 512 data points per sensor axis. One FIFO memory may hold, for example, 16 bits or 32 bits, depending on the sensor output resolution. For example, a 3-axis sensor may contain up to 16-bit x 100-points x 3-axis=48000 bits of FIFO memory. In some embodiments, the sensors of sensor package 110 may record statistics of some or each of the sensors. For example, the statistics of the high-g 3-axis accelerometer data, such as minimum, maximum, mean, median, root-mean-squared, standard deviation, and variance values may be recorded by the sensor package and, in certain embodiments, transmitted to memory module 115. In some embodiments, sensor package 110 may record burst data of the low-g 3-axis digital accelerometer data and 3-axis digital gyroscope. In other embodiments, sensor package 110 may record continuously sampled data, for example, at 1600 Hz, of the 3-axis digital accelerometer data and 3-axis digital gyroscope. Raw analog-to-digital counts for accelerometers and gyroscopes, i.e., a number representing voltage, may be recorded in memory module 115 without temperature calibration or conversion to final units. In certain embodiments, temperature calibration may be performed by processor 105 for drilling dynamics data measured by the sensors of sensor package 110. Temperature calibration may correct for the scale drift factor and offset drift over temperature. In certain embodiments, temperature calibration may be accomplished, for example, by look-up tables.

In some embodiments, ranges of some or all of the sensors in sensor package 110 may be changed while integrated data recorder 100, 200 is within the wellbore. For example, the low-G accelerometer sensing range is programmable and changeable downhole from +/−4G to +/−16G and all ranges therebetween. Ranges may be changed based on attainment of a predetermined range threshold value or by communication by downlink from the surface. Examples of predetermined range thresholds include, but are not limited to values of rotation speed standard deviation, acceleration standard deviation, or combinations thereof.

In certain embodiments, sampling frequency of some or all of the sensors in sensor package 110 may be changed while integrated data recorder 100, 200 is within the wellbore. Sample frequency may be changed based on attainment of a predetermined sampling threshold value or by communication by downlink from the surface. Examples of predetermined sampling thresholds include, but are not limited to, values of rotation speed standard deviation, acceleration standard deviation, or combinations thereof.

In some embodiments, some or all of the sensors in sensor package 110 may include an anti-aliasing filter on one or all of the axes of the sensor. The frequency of the anti-aliasing filter may be changed while integrated data recorder 100, 200 is within the wellbore. For example, the anti-aliasing filter may be changed to between 25 Hz and 3200 Hz for accelerometers. In some embodiments, the anti-aliasing filter frequency may be changed when sampling frequency is changed to avoid aliasing.

In some embodiments, integrated data recorder 100, 200 may with an MWD tool through communications port 120 or through wireless communications module 122. In one non-limiting example, statistics of downhole dynamics data (for example, maximum shock, RPM standard deviation, root-mean-squared shock, mean vibration, median inclination, etc.) may be transmitted to surface via an MWD mud-pulse telemetry, electro-magnetic (EM) telemetry, EM short-hop telemetry, wired-drill-pipe telemetry or a combination thereof. In some embodiments, the sensor data may be transmitted to the MWD tool wirelessly. For example, an at-bit integrated data recorder 100, 200 may transfer the sensor data from the bit to an MWD tool with a wireless module, via integrated data recorders 100, 200 placed at multiple locations in a bottom-hole assembly (BHA). A wireless network, such as, for example and without limitation, Z-wave, may allow the data transferred from one device to another via other wireless modules using Z-wave's source-routed mesh network architecture. In some embodiments, the MWD tool may relay the drilling dynamics data to surface via a communications channel including, for example and without limitation, mud-pulse telemetry, electro-magnetic (EM) telemetry, EM short-hop telemetry, wired-drill-pipe telemetry or a combination thereof. In some embodiments, wireless integrated data recorders placed at many different positions in a drill string may relay at-bit sensor information from a bit to surface, such as, for example, for real-time geo-steering applications.

In some embodiments, integrated data recorder 100, 200 may be positioned in an existing tool. In some embodiments, integrated data recorder 100, 200 may be added to the downhole tool without altering the tool length or mechanical integrity of the tool. In some such embodiments, a slot as described herein above may be formed in one or more components of the existing tool, and one or more integrated data recorders 100, 200 may be placed therein.

In some embodiments, integrated data recorder 100, 200 may be utilized during transportation of tool 300. In such an embodiment, integrated data recorder 100, 200 may measure one or more aspects of the movement of tool 300 including, for example and without limitation, the location of tool 300 and one or more parameters relating to the handling of tool 300 including detection of drops, shock loads, or other mishandling of tool 300.

In some embodiments, information about the operation of bottom-hole assembly (BHA) may be transmitted to the surface via mud pulse telemetry. In some embodiments, temperature difference, temperature gradient, and other drilling dynamics information may be classified into different severity levels, for example, 4 to 8 severity levels indicative of a measured condition. As a non-limiting example, in embodiments in which 2-bit severity levels (4 levels) are used, a temperature difference may be coded as Level 1 which may be between 0 and 2 degrees centigrade, Level 2 between 2 and 4 degrees centigrade, Level 3 between 4 and 6 degrees centigrade, and Level 4 above 6 degrees centigrade. Similarly, downhole acceleration events or shocks may be coded as Level 1 (no shock) between 0 and 10 g, Level 2 (low) between 10 and 40 g, Level 3 (medium) between 40 and 100 g, and Level 4 (high) above 100 g. As another example, high-frequency torsional oscillation (HFTO) may be detected with tangential acceleration measurement or angular gyro measurement with an expected frequency range, for example, between 100 and 1600 Hz. Angular acceleration can be calculated by time-differentiating the angular gyro velocity. By applying a digital band-pass, digital band-reject, analog band-pass, analog band-reject, high-pass filter, digital high-pass filter, analog high-pass filter, or a combination thereof on a tangential accelerometer or gyro, downhole HFTO events may be coded as Level 1 (no HFTO) between 0 and 10 g, Level 2 (low HFTO) between 10 and 40 g, Level 3 (medium HFTO) between 40 and 100 g, and Level 4 (high HFTO) above 100 g. Alternatively, at integrated data recorder, filtered accelerations (for example, tangential accelerations, lateral accelerations, radial accelerations, angular accelerations, axial accelerations, etc.) may be used to estimate pseudo-formation-evaluation parameters, such as pseudo-sonic log, pseudo-neutron log, pseudo-porosity log, pseudo-density log, and pseudo-Gamma log. Pseudo formation-evaluation parameters and/or their severity levels may be transmitted to surface for geo-steering.

Rock mechanics parameters (e.g. Young's modulus, Poisson's ratio, compressive strength, and Fractures) may be detected with tri-axial high-frequency acceleration measurement with an expected frequency range, for example, between 100 and 1000 Hz, as described, for example in SPWLA 2017—“A Novel Technique for Measuring (Not Calculating) Young's Modulus, Poisson's Ratio and Fractures Downhole: A Bakken Case Study”. By applying a digital band-pass, digital band-reject, analog band-pass, analog band-reject, digital high-pass filters, analog high-pass filters, or a combination thereof on the at least one accelerometer or gyro, downhole fractures may be coded as Level 1 (no fractures) between 0 and 10, Level 2 (low) between 10 and 40, Level 3 (medium) between 40 and 100, and Level 4 (high) above 100 (the numbers are without units, but correlated to the number of fractures). Rock mechanics parameters and/or their severity levels may be transmitted to surface for geo-steering.
